Data Structures: Hash Tables

Any Russians here who also noticed the "Карьера программиста" book? 🙂

Rocket speed of explanation. You should concentrate more on the concepts and talk a bit slower.. you rush like a rocket, seriously. Explain and iterate over the concepts more, bring some real life analogies and so on.

Why a linked list… Why not another array, set, an object to handle collisions.

These videos are far too complex than they need to be, atleast for me. I think it's not for beginners. Rather, it's for someone who knows this stuff, and is just looking for some revision.

3:47 was interest for me .

so a map<T, T> in C++, right?

interesting video with terrible voice is bad way to learn something

Very nice video. Thanks!

I have an interview with Yahoo in 3 hours ???

HashMap and HashTable, which one is better to use?

you need to slow down girl!

THanKS you! One of the best teacher I ever Seeeeen!

The accent of the speaker is very poor; words not clear

This is writing is unreadable.

why is/should the return value of the 'put' method be of boolean type?

This whole time I've been using hash tables, I had no idea it's underlying implementation details! So cool!!

The class hashtable starts like this :
Class Hashtable{
LinkedList[] data
….
}
The variable data should be an arrayList in order to have the complexity of O(1) when getting one element . Am I missing something?

A few times when it's easier to read a book than watch a video…

i dont have my own time

aka Maps

这个解释也太蠢了，还好不是我一个人这么评论，这个程序员让我怀疑人生

Yeah, I don't intend this to be negative. However, I think your strategy to break down Hash Tables is too messy. I would refrain from adding unnecessary clutter on your video (Left Column) and simply just talk about it. This would probably help out the most when trying to break down a complex Data Structure into something more easily understandable!
No offense! We are all here trying to learn. Thanks for posting!

What does "fix this value immediately" mean? @4:40

Does anyone know which software she uses to draw?

Nice one

Proof

Hash tables are amazingly fast. My new favorite data structure. The only downside is they take up a lot of space when they get large

What is method used to match a hash code with an array index?

can you tell me what if there are multiple values of Alex or key in hash map
?

Not a good video, a concrete example would be better instead of a1 a2's everywhere without any meaning

People complaining that they don't understand what she is explaining, you guys need to first do your own research on what a hashtable is. This video is not supposed to teach you how to build one, but it explains what a hash table is and how it works behind the scene. And I am quite confident that she has done a very good job of explaining it. One tip of advice: Do your own research first before watching a tutorial on it. This way, you will be able to fill in the gaps that you had while researching.

Worst video I’ve ever watched on YT. blahblahblah she cannot code.

I love all your other videos/explanations but this one left me a bit confused honestly… ?

that was Clear, but i have to watch the 6 mintue video for 20 min going back and forth 😉

more confused after watching this video

Please refer to the actual source code as well

listening your talking, just pissed me off!

These arent data structures. This is criptography

HORRIBLE!!!!

Great refresher on a topic that I vaguely remembered. Thanks.

You cant just have a bunch of info on the screen at the same time. Poor presentation.

This video proves why Indians make the best youtube tutorials for academics. 😛

Horrific explanation. I'll put something together on my own time and get back to you.

this women is gifted!! i love all her teachings!

Don't mind, but the voice is very annoying.

++ subscribed would watch again…

Poorly explained, focused only on what it is and not why it exists in the first place. Disliked, sorry.

This doesn't look like a kitchen?

wasted my time
